So I’m at the car wash and notice that the guy that’s finishing it off is putting in a lot of effort; towel between every wheel spoke, inside the car wiping every corner of every window etc. So I put the 3 singles back in my pocket and pull out a five. I walk over to his boss and tell him I noticed, and that this guy ROCKS. When I claim my car, I compliment him with the best non-profane Spanish words I have (I learned what little I know as a bartender - it’s not PG) and give him the five. Dude’s face LIGHTS UP. Jim Rohn used to say that if two figures occur to you when tipping — always go with the higher one. Thanks Jim. Great ROI today!
